SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 564,869, dated July 28,1896.

Application filed April 9, 1896. Serial No. 586,807. (No model.)

To all whom, it may concern:

Be it known that I, ALEXANDER COLE, a citizen of the UnitedStates,residing at Bridgeton, in the county of Cumberland and State ofNew Jersey, have invented a certain new, useful, and valuableImprovement in Spring Bed-Bottoms, of which the following is a full,clear, and exact description.

My invention has relation to spring-bottoms for beds, &c.; and itconsists in the novel construction and arrangement of its parts, ashereinafter described.

In the accompanying drawings, Figure 1 is a top plan view of a bedsteadwith my springbottom attached thereto. Fig. 2 is a sectional view of thebedstead and .part of the spring-bottom, showing how the bottom isattached to the bedstead. Fig. 3 is a detail perspective view of amodified form of the spring-wire.

The bottom consists of spring-wires 1 1, which extend from the head tothe foot of the bed. Each wire is provided at certain intervals with theloops 2 2. The said loops in the adjoining wires 1 1 are opposite eachother and extend across the bed in substantially a straight line. (SeeFig. 1.) The rubber pipe or wooden rods 3 rest in said loops 2 2. Saidrods extend across the bed, as shown in Fig. 1. At each end the wiresare provided with a perpendicular portion 4:. At the foot of the bed theperpendicular portions 4 4 of the wires pass behind a lateral strip 5,said strip 5 in turn being secured to the footboard of the bedstead. Theback of the strip 5 may be provided with recesses to receive theperpendicular portions of the wires 1 1. Said strip 5 may extend all theway across the foot of the bed or it may be made up of sections 6 6, asshown in Fig. 1, each said section being secured to the foot-board ofthe bedstead as above described.

At the head of the bed the perpendicular portionsA. of the wires passbehind the lateral strip 7. The back of the said strip 7 may also beprovided with recesses to receive the perpendicular portions of thewires, and the said strip 7 may also be made in sections, as

described for strip 5. The strip 7 is provided with a number ofthumb-screws 8 8. Said thumb-screws pass through the strip, and theinner end of the screw is adapted to bear against the perpendicularportion 4 of the end of the wire, as shown in Fig. 2. Thus the tensionof each individual wire may be regulated by releasing the thumb-screw 8and drawing the wire tighter or loosening it as the case may require,and then the thumbscrew can again be brought to bear against the end ofthe wire and hold the wire firmly in its proper place. The wires may bedoubled, as shown in Fig. 3, or they may be placed together in largernumbers without departing from the'spirit of my invention.

The sections composing the cross-strips 5 and 7 may each be providedwith any number of wires and as many sections may be used as the widthof the bedstead will require.

The mattress of the bed will rest on top of the spring-wires 1 1, andthe cross-rods 3 3 possess sufficient elasticity to make the bottom atall times yielding, and at the same time the said cross-rods prevent thespringwires 1 1 from being bent or pressed out of shape. The cross-rods3 3 are just a trifle smaller than the loops 2. (See Fig. 2.)

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

In a spring bed-bottom a number of wires extending from the head to thefoot of the bed, each wire having at its end a perpendicular portion,lateral strips secured to the bed, said strips having recesses, saidrecesses receiving the perpendicular ends of the wires, thumb-screwsextending through said strips, each said thumb-screw adapted toindependently impinge one perpendicular end of a wire against the bed.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER COLE.
